When trigonometry meets savage burns! The meme instructs you to set your calculator to degrees (not radians), then calculate the sine of your age. The punchline? "It's less than 1" - which is mathematically inevitable since sine functions always output values between -1 and 1.
It's basically saying "I know you're old without saying you're old" with mathematical precision. The genius part? Even if you're 90, the sine value is still approximately 0.894... proving that math can deliver burns with decimal-point accuracy!
